Hi Unmesh,
If you configure multiple seed nodes, then only at least one of the has
to be up for new (or restarted) members to join.
In our deployment we have a pretty static membership (we don't add nodes
dynamically), so we set all nodes to be seed nodes, no harm in that.
Hope that helps,
Michal

Hi,
As of now, if seed node is shutdown by SIGINT (or doing Crtl-C), it
leaves the cluster gracefully. This means it is removed from the
membership list on all the other nodes in the cluster. If such a seed
node is restarted, there is not way for it to re-join the cluster,
unless there is another seed node up and running. If we can have a
periodic snapshot of group membership list stored on all the nodes, it
can attempt to rejoin the cluster using the snapshot, without needing
another seed node.
Looks like Serf has this
feature.. https://github.com/hashicorp/serf/pull/87
Is there any way to do this in Akka cluster?
Thanks,
Unmesh
